with his back. he has been struggles with his back. he has been sidelined for 15 months. he returned to action earlier this year. he won his first major at the masters 20 yea rs his first major at the masters 20 years ago. in a statement on his website, he says, i will not be competing, i did everything i could to play, but my rehabilitation did not allow me time to get tournament ready. i have no timetable for my return, but i will continue my diligent effort to recover, and we'll get back out there as soon as for. roger federer will play rafa nadal in the final of the miami open tomorrow. he beat nick kyrgios over three tough sets, each went to a tie—break. the 18 time major winner w011 tie—break. the 18 time major winner won the decisive third, and continues his good start the, having w011 continues his good start the, having won 18 of 19 matches in 2017. the final will be a repeat of this

yea r‘s final will be a repeat of this year's australian final will be a repeat of this yea r‘s australian open, final will be a repeat of this year's australian open, which federer won. and at six o'clock this evening, johanna konta is in action in the women's final in miami, the first british woman to get there. she plays caroline wozniacki for what will be her biggest title to date if she can beat. that will be her third title on the wta tour. and mark williams is through to the final of snooker‘s china open. he dominated the match including making this century break to go four frames up. he will face either kiran wilson world number one mark selby in the final. and that for the moment is all the sport. 0ver final. and that for the moment is all the sport. over on the bbc website at the moment you can watch the world figure skating championship live from finland at the moment, the men's free skating happening at the moment. that is all from me at the moment, back to you, julian. john watson, thank you very much. now on bbc news it is time for

that click. this week: adventures in sound with posh cams, invisible speakers and cloning brian eno‘s brain. today i'm in the lair of the wizard who likes decibels, who likes to write a book or two, a wizard called brian eno. don't know if i should show you how this works. let's just find the... these are just not bits of speakers,

they are working speakers? yes. on my gosh. and it is sound that this man is best known for. big sound. the former member of roxy music has added production sounds to the biggest acts in the world — u2, coldplay and some chap called bowie. he is a self—proclaimed non—musician who uses technology to make his art. there it is. so this essentially never repeats in billions of years. it is constantly generating new images. i mean, sometimes it does things that are so baffling and fantastic you think,

i never would have thought of that. it is love of random, generative art that has brought us here. his music is very atmospheric and at the wheel and he's regarded as the godfather of ambient music and his new work, reflection, it is rather unpredictable. it is a generative music app which follows rules defined and we find by brian eno but which plays differently every time. 14% of these notes, random, will be pitched down by three semitones. the second is a1% go an octave down, 12 semitones. can ijust said... scientist. i would go further, quantum scientist. probabilities. brian eno has spent weeks, months, tweaking these rules and probabilities

which when combined course these sounds to bounce, transform or not play at all. these are different types of scripters. i like them. who doesn't! actually, these rules can be applied to any type of music. something more pacey, their effects become immediately obvious. we will make that a tedious loop. a lot of music is based just on things like that and it goes on for ever. now i will put in some scripters. first a way of reducing the number of beats. it is only playing 80%.

already it is a pretty crappy drummer. actually, this is way more interesting than the original drumbeat. we'll introduce some rolls. traditional music, you have a piece which locks down but you are not blocking it down. you are taking these and locking that down, the process. i don't mind so much if the piece changes every time. it is a good way of explaining it. i am trying to make a version of me in the software, my taste, if you like. i'm interested in the edge

of my taste envelope, and randomness is a way to find out. mixing things up is something brian is known for. the legendary oblique strategy cards, by imposing a rule, you reduce the possibility to solve it. discover the recipes you are using, and abandon them. if you are working with other people, you get information and derailment. if you are working alone you can easily get into a rut. work at a different speed. that is a useful one. that could mean a lot of different things. it could change the speed or do things at different speed. work very, very quickly or very, very slowly. take a minute to get to that guitar. pick it up.

put it on. plug it in. have you thought of whether you can copyright the music that comes out? that is a good point. if you sell the app, do they own the music? because they have constructed it. all the bits i never the final construction is that there is. and what did you conclude? it is not easy to make a case for saying it is my music because it sort of is in a modern sense of what composing means. we spent about an hour with eno, and in the next few days you can see more inside brian's brain on online. lookout for the link on twitter from click. the week in tech, elon musk started yet another company.

the company which aims to implant ai technology onto the human brain. does this guy never watch sci—fi films? it rarely ends well. and was on the head honcho showed the interior space tourists will see in his 0rigin spacecraft. jeff bezos is now the second richest man in the world with a net worth of $75 billion. $10 billion behind bill gates, though. and how about turning any surface into an interface without the need for a screen? a host of devices that like speakers lights and thermostats can beat all the remote controls. in france, a host of teams will outline vehicles built with less than a number of parts. they may someday drive around the

human body performing medical procedures. but now, teams will raise them at speeds of up to five nanometres per hour. 37 million years to travel a single mile. not exactly formula one. this week, samsung launched its latest mobile phone. just a few minutes to go until the launch start, and there is an incredible level of secrecy here, but there is a lot at stake for samsung. after the note seven debacle, all sat we're waiting to see why the s8 has in seoul. cold hard facts — phone...

well, two phones were born. s8 and s8 plus. not even the plus is that large, because of the screens on both of them curve over the edges. a lot of hype about these. it does not feel like a big deal personally, but it means you get a screen which is bigger on a smaller size. so, a few of the features we have been told about today. a fingerprint scanner. iris and facial recognition, meaning you should not need a password but still achieve all the security you want. an invisible home button. as you press it, you can feel some sensation. one thing we have had a lot of talk about is the launch of this. the launch of bixby. when fully functioning, the system

aims to make interacting easier. interacting with apps, controlling other devices and using artificial intelligence to land your habits and suggests what you might be looking for next. naturally, i want to test this new personal assistant, but there is a substantial problem. bixby is currently only available in korean. it will be released in american english in may. after that, other languages will follow. it may well be great, but i can't tell you about it. in the meantime, the image recognition function is in action. you photograph a night, and it aims to find it for you online, with varying success. so, the hairbrush shot. it thinks my hairbrush is a fork. i have been asking around to see what others think about it. very impressive screen. 18.5 by 9.

i think that will be a huge trend in phones this year. that is a big screen in a very small phone. 5.8 inches, and i can fit my hands around it. the experience has not changed a lot. we have not got the dual camera. bixby only uses standard samsung apps. i do not think everybody wants to speak to standard apps. they want to speak to all their apps. for the amount of time they made us wait, these perhaps under—delivered on standout features we have not seen elsewhere. the phone will be released this month from $650. the company believe they will see explosive sales, but let's hope not exploding phones! now to cyborgs, and when hollywood imagines them they look way too futuristic to be anywhere close

to becoming reality. they did not save your life, they stole it. but are they? dan simmons has a special appointment with a professor at the university of tokyo in japan. i have come to see a professor who is apparently going to turn me into some sort cyborg. it is one of the first times a camera crew has been allowed in to see the process happen and it will take place through this door here. this research team have come up with the world's

thinnest organic circuits, lighter than a feather, they could be worn like a second skin. either monitoring the body or as an e—skin display. we can introduce the electronic functions on the surface of the skin without causing any discomfort from wearing. this is human and machine coming together. the display they are putting on to me has taken three days to manufacture so the research team are being very careful. its thickness is just two to three microns. the magic is controlled by polymer semiconductors and transparent electrodes with organic semiconductors and diodes firing up the display. and they are surprisingly resilient. they can scrunch them and on rubber even stretch of them. it still works and that is something

i have come to put to the test. the professor has used his e—skin to measure heart rate and oxygen levels in the blood. could we use these out and about, is it robust enough to go running with it? please move your hand. something like that. i see. it doesn't cause any mechanicalfailure. it is flexible. would you expect us to change this every two or three days? yes, that's another possibility. if we can manufacture everything very cheap, so after you go to the shower and then delaminate your skin and put on the fresh one. i expected that to break by now. and it's still very much alive. this is just a single

digit display today, but what could this be in the future? the second step will be much more digits and then going to the high—definition display. so we could have maybe 1,000 pixels? yes, that's technologically possible. on our hand, so we could, what, talk to people on our hand? yes. this could be a picture of my mum, for example? she would appear on my hand? yes, that would be possible in the future, maybe four to five years. but lifetime will be the biggest issues. this is the start of the rise of the cyborgs. that was dan, wearing some pretty advanced technology on his person.

i've got my own piece of advanced technology here. these are the sennheiser he1 headphones and would you like to take a guess at what is special about them? for a start, they cost £54,000! fire up one direction. no one direction? classical music plays. 0k. so, i'm not a real audio expert. i used to work on the radio so i do know about sound. but i'm also 43, so i think i'm slightly deaf. but these certainly sound very expensive. what's interesting is that they're not noise cancelling and they‘ re not sound isolating. i can actually hear other stuff in the room. and i'm not sure whether i would

expect that or whether i would expect to be shut off from the room when i put this on so you can just hear music. wow! for people who are in love, or should i say obsessed with sound quality, it seems that nothing is off—limits. but when those people are injapan, off—limits hits a whole new level. we are used to seeing unusual things in japan, so we were not surprised at all to hear about a group of people who would think nothing of spending a whole lot more than the price of these in search of audio perfection. music: "the four seasons" by vivaldi. it seems some people don't care what their place looks like,

as long as it sounds amazing. but if you are into your high—end audio but you also want something a bit more inconspicuous, then we've come here to london's smart apartment to see some options. these speakers are made by linn and will cost £12,500 for the pair. they come with a choice of fabrics. you can choose whichever one blends into your decor best. the fabric, apparently, has been specially developed so it doesn't dull the sound. but metre—tall speakers are always going to be quite attention grabbing. what if you want your speakers to be heard but not seen at all? so, can you spot the speakers in this room? well...

they are actually up there. there are lots of little speakers in the ceiling next to the light fittings. they were installed before plastering, so that they can sit flush with the ceiling. this is what they actually look like and because there's quite a few of them they don't have to be that loud to fill the room with sound. if that's still too conspicuous for you, this room has invisible speakers in that they are in the walls. you can feel them by the vibration here and here. you can't see them at all, of course. these ones have been wallpapered directly over. if you are plastering the wall you can get away with two millimetres of plaster only, apparently. and if you are worried about your speakers going wrong, the manufacturers have told us that within 15 years they will come and not only repair the speakers but also make good your decorations. and that's it from the smart apartment. follow us on twitter

if you would be so kind. we have plenty more of this kind of stuff every week and there's more coming from brian eno soon. thanks for watching and see you soon. well, it has certainly not been sunny all round this morning. some of us woke up to quite heavy rain, particularly if you live in wales and north—western parts of england. today, we have got sunshine and showers on the way. this is the cloud that brought the rain across the south—west into wales and then the northwest. but many of these central and eastern areas woke up to sunshine. today, it is a real mixed bag in the afternoon, so hit and miss showers, you will get the sunny

spells but then you might get a downpour as well. let's take a closer look across southern parts of the uk around the middle of the afternoon. hit and miss showers, some of them hail and thunder as well. coastal areas looking pretty good. if you're heading off to bournemouth or brighton, looking out to sea it will be clear and blue, but inland, you will see the showers growing. lots of breaks between the showers, you can see the definite blobs, hit and miss weather. some of us might get a downpour of hailstones, others will be dry. if you stay dry and sunny through the day, consider yourself lucky. the showers will fade through the course of the evening. by the time we get to 9 o'clock there will be very few of them around. we are left with clear skies overnight. it will be quite chilly this coming night, just cold enough for a grass frost across northern areas of the uk, but to the south it will be milder, around eight degrees in norwich and in london. sunday is a very different day.

two very different days this weekend. from a showery saturday to a much sunnier sunday. this high pressure means that the weather on sunday should be sunny from morning until the afternoon and evening. dawn until dusk. fine wherever you are, really, just a few scattered clouds here and there. temperatures on sunday will be more or less what we will get on saturday, but the fact there will be more sunshine around, less rain, it will feel warmer, 16 in london, cooler on the coast, 12—13 degrees. on sunday, we have got the boat race, 0xford against cambridge, tradition there. partly cloudy skies, some sunshine around and temperatures in the midteens. the weekend forecast, april showers today, very hit and miss, a chilly night on the way, and then a sunny sunday. enjoy. good afternoon. the government has said that britain will defend the interests of gibraltar during the brexit negotiations, following warnings that spain is attempting to use the process to regain sovereignty of the rock.

the eu has suggested that a brexit deal won't cover gibraltar without a separate agreement between london and madrid.
